Nearly Amazing but still good and worth the price
on 29 July 2014
it is a nice metal construction, I ordered the 58mm, but watch out as the front side will not take a 58mm lens dust cover, even though the thread to the lens side on the reverse fits a 58m, it is larger than 58mm on the obverse side towards the shot subject, possibly to reduce vignette, at full depth of darkening it picks up a cross shape, as it works similar to a pair of Circular Polarizing Filters together at 90 degrees to each other, however at lesser darkening levels it works really nicely no spotting as others have mentioned, smooth running ring, my camera focuses really nice through this, the optical glass looks of a good quality, great for it's price, I however think that I will need a darker ND filter for what I am looking to achieve, so daylight long exposures for silk smooth waves at the seaside will need something stronger than ND 400, possibly a ND 1000.
